concrete lintels

I'm taking out a garage door and putting in man door. I'm thinking about using the concrete lintel that was over the garage door. The lintel was made up of 2 4" x 8" lintels with a gap between. Should this gap be filled with concrete? I'm also thinking about a steel lintel. This might be easier. Is this simply a piece of angle iron? If so what size for a 38" rough opening? How do you incorporate the vertical part of the angle into the wall?

Thanks for your ideas.
Jerry

Not enough information to make a guess -

I assume your wall is an 8" thick block wall. Does it have a brick veneer or is it just a plain block wall?

If the lintels you have are precast concrete or pre-made block lintels, they would have steel in them. It is not necessary to fill the gap between the lintels if the wall is block

Is the wall loadbearing? How wide is the required masonry opening for the door you are thinking about?

If the wall does not carry any load, you could just build a "buck" to create the rough opening. You then brace/prop the bottom, build a new 8" thick by 8" high lintel/bond beam, put in some rebar and fill with grout/concrete and then remove the props after a few days or a week, depending on the temperature. A man door does not have a wide opening, so the load (if any) on the lintel is very low and is just used for continuity.

Yes, 8" block wall with no veneer.

The lintel is precast.

Rafters will sit on this wall so it's load bearing.

The required masonry opening for the door is 41".

Thanks
